We may be observing the first steps of parapatric speciation in the grass species Anthoxanthum odoratum (at right).Evolution is a change in the inherited characteristics of a population over time through the process of natural selection, which may result in the formation of new species. Natural selectionEcological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.Species that arrive first in a newly created environment (such as an island rising out of the sea) are called pioneer species, …Evolution in organisms occurs through changes in heritable characteristics—the inherited characteristics of an organism. In humans, for example, eye colour is an inherited characteristic and an individual might inherit the "brown-eye trait" from one of their parents. Vertebrate Evolution.

The first person who explained how evolution happens was Charles Darwin with his scientific theory of natural selection.The basic theory of evolution is surprisingly simple. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either ...So evolution originally referred to the supposed series of changes that a species was predetermined to undergo, in the same way that an embryo is preprogrammed to develop.
